ABSTRACT
The composition of volatile oil from Juniperus coahuilensis berries (seed cones) in fox scat is
very similar to that of berries taken directly from trees. The most notable difference is that the percent
yield is significantly higher from scat than intact fresh berries. This may be partially explained by the fact
that the scat berry has been partially masticated and thus amenable to steam during distillation, whereas
A
the fresh seed cones have their skin intact, impeding the loss ofterpenes in distillation. second factor is
that sugars, starch and protein may have been partially removed during digestion. Thus, the yield from
the 'depleted' berry would naturally contain a higher percent volatile oil relative to remaining cellulosic
pulp. The gray fox does not extract most of the terpenes from juniper berries. The nearly intact berries,
containing most ofthe terpenes, are excreted in the scat. This undoubtedly results in the loss of some or
considerable amounts of nutrients, but the food source is so plentiful, that the loss of nutrients, due to
incomplete digestion, may not be significant to the health of the gray fox. Published on-line

KEY WORDS:
Juniperus coahuilensis, volatile oils, gray fox scat, terpenes, composition.
Based on identification of plant material in gray fox Urocyon cinereoargenteus) scat, White et
(
al. (1999) found that gray fox obtained over half (51.3%) of its diet from Juniperus osteosperma berries
(seed cones) in eastern Utah. They also reported that gray fox is adept at climbing trees and may have
used juniper trees for resting, food source, or as escape cover. Analysis of the berry hull (pulp
surrounding the seed) in different seasons, over two years, showed the hull was about 63 - 68% of the
whole seed cone. The hulls (pulp) contained 3.8 - 5.2% protein, 15.9 - 28.3% starch and sugars, 25.8 -
26.8% crude fat, and 27.4 - 32.1% ADF
(Acid Detergent Fiber). The juniper seeds
were not digested by gray fox.
The summer of 2013 presented a
remarkable year for the production of a
bumper crop of seed cones (berries) of
TX
Juniperus coahuilensis near Alpine, (Fig.
1). Notice the limbs are loaded with berries
and leaning. Many branches were so loaded
with berries that they drooped to the ground.
Careful observation revealed that in
Nov. and Dec. 2013, gray foxes were feeding
almost exclusively on the seed cones of J.
coahuilensis and these seed cones accounted
for ca. 90% ofthe volume in the scat (Fig. 2). Fig. 1. J. coahuilensis with branches loaded with fruits.
120 Phytologia (Apr 4, 2016) 98(2)
Gray foxes were often seen feeding on freshly fallen berries on the ground (Fig. 3), or up in a
juniper eating the berries directly from the limbs (Fig. 4).

In addition to gray fox, mule deer Odocoileus hemionus) ate berries from the ground (Fig. 5) or
(
even resorted to considerable effort to eat berries directly from the trees (Fig. 6). Western blue birds also
fed on J. coahuilensis berries, both on the ground (Fig. 7) and in trees.

Cunningham, Kirkendall and Ballard (2006) reported Juniperus monosperma berries accounted
for 0.0 - 22.5% of the gray fox's diet and from 0.0 to 18.25% of the diet of coyotes in central Arizona.
Thacker et al. (2011), by analyzing the terpenes in fecal pellets of greater sage-grouse in Utah, correctly
identified the sagebrush species that the sage-grouse was feeding on using crude terpene profiles.
As far as known, there are no reports on the composition ofessential oil ofJ. coahuilensis berries
present in fresh gray fox scat. The composition ofthe volatile leafoil ofJ. coahuilensis has been reported
(Adams, 2000, 2014), but there are no reports on the composition of the volatile oil of the berries (seed
cones).

The changes in terpenes during passage through the gray fox digestive tract are not known. The
purpose ofthe present paper is to compare the volatile oil compositions offresh J. coahuilensis seed
cones vs. fresh fox scat in which ca. 90% ofthe scat consisted ofJ. coahuilensis seed cones.
MATERIALS AND METHODS
Fresh, mature seed cones were collected from J. coahuilensis trees in Dec., 2013 at the home of
Mike and Shirley Powell, approx. 8 mi se of Alpine, on Tex 118, thence e 2 mi on Mile High Rd., 30°
16.147' N, 103° 33.522' W, 5324 ft (1623 m). Adams 14649-14653 ripe seed cones of J. coahuilensis
;
Adams 14654-14658 fresh fox scat was collected at the small location and frozen. Leaves for volatile oil
,
were collected from J. coahuilensis 85 km north ofLa Zarca, Durango, Mexico, Adams 6829-6831.
,
mg
Fresh frozen J. coahuilensis seed cones (13-33 g) were co-steam distilled with 2 of undecane
mg
and 2 methyl decanoate (internal standards) for 2 h using a circulatory Clevenger-type apparatus
(Adams, 1991). In the same manner, individual frozen fox scat (3.88 - 8.74 g) were distilled. The oil
samples were concentrated (diethyl ether trap removed) with nitrogen and the samples stored at -20° C
until analyzed. The extracted scat and leaves were oven dried (48h, 100° C) for the determination of oil
yields.
MSD
The oils were analyzed on a HP5971 mass spectrometer, scan time 1/ sec., directly coupled to
a HP 5890 gas chromatograph, using a J & W DB-5, 0.26 mm x 30 m, 0.25 micron coating thickness,
fused silica capillary column (see Adams, 2007 for operating details). Identifications were made by
HP
library searches of our volatile oil library (Adams, 2007), using the Chemstation library search
routines, coupled with retention time data of authentic reference compounds. Quantitation was by FID on
an HP 5890 gas chromatograph using a J & W DB-5, 0.26 mm x 30 m, 0.25 micron coating thickness,
fused silica capillary column using the HP Chemstation software.

RESULTS AND DISCUSSION
The compositions ofthe berries in the fox scat are very similar to berries taken directly from trees
(Table 1). The most notable difference is that the percent yield is significantly higher from scat than
intact fresh berries (Table 2). This may be partially
explained by the fact that the berry skin and layer of
wax was somewhat disrupted by mastication in the scat
(Fig. 8), whereas, fresh seed cones remained intact
during distillation. Thus, the pulp was more easily
A
subjected to steam in the scat berries. second factor
is that sugars, starch and protein may have been
partially removed during digestion. Thus, the yield
from the 'depleted' berry would naturally contain a
higher percent volatile oil relative to remaining
A
cellulosic pulp. third factor might be the enzymatic
removal of glucosides attached to terpene-glucosides,
leaving free terpenes that easily volatilize during
A
distillation. fourth factor is that the scat berries and
tree berries likely did not come from the same tree.
Notice the composition of the berries from tree 14649
is more like that of the scat berries for a-pinene,
terpinolene and terpinen-4-ol. It is possible that the
scats collected did not come from any ofthe trees from Fig. 8. Fox scat with J. coahuilensis berries,
which berries were collected.
From the current limited study, one can not say which factor was most important (or ifthere may
be additional factors, not considered).
Several terpenes are in larger concentration (Table 2) in the scat: a-pinene, sabinene, and the
three diterpenes - abietadiene, 4-epi-abeital, and abieta-7,13-dien-3-one. Two terpenes are larger in the
cones: terpinolene and terpinen-4-ol (Table 2).
The volatile berry oils differ in many components, both quantitatively and qualitatively, from the
volatile leaf oil ofJ. coahuilensis from La Zarca, Mexico (Table 3). This likely reflects both ontogenetic
variation between berries and leaves as well as geographic variation in the leaf oils of J. coahuilensis
(Figs. 4, 5, Adams, 2000). Although, Adams (2000) found the leafoil from Alpine, TX to be very similar
to that from Ciudad Chihuahua (CM), north ofLa Zarca.
Although there appear to be no reports on the fate of terpenes in gray fox, there are a few such
papers on small mammals. McLean et al. (1993) fed Eucalyptus radiata leaves to ringtail possums and
found terpene derived metabolites increased in the urine. They concluded possums detoxify dietary
terpenes by polyoxygenating the terpenes so the highly polar metabolites will be water soluble and
excreted in urine.
Boyle et al. (2000) fed p-cymene to Koala and found no p-cymene or metabolites in the feces, but
oxidized metabolites of p-cymene were excreted in urine; a very similar mechanism as found in possum
(McLean
et al., 1993).
Other methods of detoxifying Juniperus terpenes in woodrats (Neotoma) are discussed by Adams
etal. (2014,2016).

In conclusion, it appears, in this preliminary study, that gray fox does not extract most of the
terpenes from juniper berries. The nearly intact berries, containing most of the terpenes. are excreted in
the scat. This undoubtedly results in the loss of some or considerable amounts of nutrients, but the food
source is so plentiful, that the loss ofnutrients, due to incomplete digestion, may not be significant to the
health ofthe gray fox.
